According to MMC-3 (or any later versions) READ TOCs are mandatorycommands and have nothing to do with CDC_PLAY_AUDIO. I have no ideawhy the check was put there in the first place but it now only breaksautomatic actions on certain drives.

Note that this test was only effective when ide-cdrom was being usedas sr didn't mask CDC_PLAY_AUDIO according to the capabilities.
